SPECIFICATION forming part of Letters Patent N 0. 734,853, dated July 28, 1903. Application filed May 16 1903. Serial No. 1 57,373. (No model.)

United States of-America, residing at Tarentum, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Rail-Joints, of which for its object the provision of novel means whereby said rails may be rapidly and easily connected together withoutthe use of bolts or nuts, asnow generally used.

Another object of our invention is to provide a rail-joint which will be highly eflicient in operation, strong and durable, and compara I tively inexpensive to manufacture.

Briefly described, our invention comprises two rail-sections, one of said rail-sections carrying a double-wedge-shaped portion, which is adapted to be seated in the double-wedge- I v shaped recess formed inthe corresponding section. To provide means for strengthening said connection or joint, we form an enlarged portion upon each side of the rail and integral of Fig. 1'.

with the web of said rail, whereby when the same are joined together the lateral expansion of the same will be prevented. H In describing the invention in detail reference is had to the accompanying drawings, forming a part of this specification, and wherein like numerals of reference indicate like parts throughout the several views,in which Figure 1 is a top plan view of our improved rail-j oint, showing two sections of a railj oined together. Fig. 2 is a side elevation of the same. Fig. 3 is an end view of one of the sections. Fig. 4 is a cross-section taken on the line 4. 4c

Fig. 5.is an end. view of the corresponding section. Fig. 6 is a detail perspective view of the end of one of the sections. Fig. 7 is a detail perspective view of the corresponding end.

To put our invention into practice, we provide a section of the rail having an enlarged double-wedge-shaped portion 1, said doublewedge-shaped portion being formed integral with the head, web, and base of said rail, the

. web of said rail portion or section being cut away, asindicated at 2, and the head of said rail being cut away, as indicated at 3. In the corresponding section of the rail-section we provide a double-wedge-shaped recess 4:, formed in the head and base of said rail, also in the-web of said rail, as indicated at 5. The web portion of this rail is strengthened or braced by the enlargements 6, said enlargements being formed on both sides of theweb and projecting over the base thereof, while the head of said rail. When it is desired to join the two sections of the rail together, the section 1 thereof is placed in vertical alinement with the corresponding section,when the double-wedge-shaped enlargements are carried vertically into the double wedge shaped recess i when the same is in position to be used.

, While we have herein shown and described our invention in detail, yet it is obvious that we may-form the enlargements upon the sides of the web of a rail of any desired shape or size. It is also obvious that the angle of the double-wedge-shaped enlargements and recess'employed in our invention may be of any angle found practical to our invention. It

will be further noted that various changes "upper edge of said enlargements supports the may be made in the details of construction without departing from the general spirit of our invention.

Having fully described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. A rail-joint comprising two sections, one section of said rail carrying an enlarged double-wedge-shaped head or enlargement, said enlargement fitting into the double-wedge- Intestimony whereof We aflix our signatures in the presence of two itnesses.
